  • a significant advantage of the present invention is the provision of means for providing a preliminary wrapping of plastic sheeting about the compressed bale before the bale chamber is opened, so as to maintain the integrity of the bale during the subsequent wrapping process. It is known that when compaction pressure is released from a bale of fodder there is a tendency for the bale to expand. Also, the bale may disintegrate unless it is restrained, for example by cord or netting. In conventional stand-alone baling machines it is known to provide means for wrapping netting about the bale before it is released from the baling chamber. However, the disadvantage of netting is that it does not seal the bale.
  • bale It is highly advantageous to seal the bale and keep it as dense as possible because this lowers the incidence of fermentation, and helps to hold the sugars in the fodder thus maintaining its feeding value during storage.
  • Manufacturers of conventional baling machines have attempted to replace netting with plastic sheeting but this has not been successful.
  • the invention provides means for wrapping the compressed bale 20 with plastic sheeting before the pressure is released from the compacted bale on opening the bale forming chamber 10.

  • the rotatable roller 30, which has a width greater than the width of the baling chamber 17 (e.g. a width of 1400 mm as compared to 1200 mm for the baling chamber), carries a roll of plastics film 31.
  • the leading edge of the plastic sheeting 31 is fed between a top feed roller 32 and a lower feed roller 33, and between the lower roller 33 and a pinch roller 34.
  • the rollers 32, 33 and 34 all extend parallel to the roller 30.
  • the leading edge of the plastic sheeting 31 is pinched between the rollers 33 and 34 and is fed downwardly to engage between the rollers 15, 16 and the peripheral surface of the bale 20.
  • the plastic sheeting is thus pulled around the outer cylindrical surface of the bale 20 as it is carried in a circular path around the bale surface by the rotating rollers 15 and 16. This motion draws the plastic sheeting 31 from the roller 30 and simultaneously rotates the rollers 32, 33 and 34.
  • the lower feed roller 33 is geared to rotate at a faster peripheral speed than the roller 32.
  • the gearing is such as to stretch the plastic sheeting 31, as it passes between the rollers 32, 33, to from 130% to 170% of its original length. It is this pre-stretched plastic sheeting which is wrapped about the cylindrical surface of the bale 20. This offers a number of advantages.
  • the plastics is pre-stretched it prevents the bale 20 from expanding when the compression chamber is opened and the pressure of the upper rollers 15 is released from the bale.
  • the amount of plastic sheeting needed to provide a preliminary wrapping of the bale 20 is much less when the plastics is pre- stretched.
  • the two opposite edges of the plastic sheeting are caused to wrap around the end corners of the bale 20 to form an overlapping wrapping strip 35 (see Figs. 1 and 8) on the flat peripheral edge portions of the bale.
  • the webs of wrapping material are applied to the surface of the bale 20. Because the bale is rotated about its horizontal axis as the wrapping takes place, the webs 36 cross each other at an obtuse angle which, in the first part of the wrapping process leaves triangular shaped pieces 37 with less cover at the peripheral end part of the bale.
  • the overlap 35 formed by the pre-stretched initial wrap effectively covers the exposed triangular shaped parts so that less subsequent wrapping of the bale is need to achieve a full wrap.
  • a means is provided for loading the roll 30 of plastics film, or alternatively a roll of netting, into the cylindrical housing 66.

  • FIG. 2 another aspect of the present invention resides in a locking mechanism for locking the upper part 11 of the bale forming chamber to the lower part during the compaction of the bale. Because of the pressures exerted within the baling chamber during the compaction of the bale, it is important that the upper chamber part 11 is locked against vertical movement relative to the lower part 12. This is achieved by means of a hook 40 mounted on the upper part 11 which engages with a latch 41 on the lower part 12. There is a hook and latch on each of the two sides of the machine.

  • the platform 130 is fixed, and is circular in plan and in the lowermost position of the chamber 107 it fits within the bottom of the chamber 107.
  • a first bale wrapping means is provided at this location. As shown in Figure 16, this comprises a vertically disposed support arm 193 which carries a film dispenser 194.
  • the support arm 193 rotates, in a circular path, around the circumference of the chamber 107.

  • the compaction head 115 rotates, about the vertical axis, around the inside perimeter of the chamber 107 with the cleated rollers constantly rolling over the top surface of the grass as it is compacted and builds up in the cylinder to form a bale 20. Simultaneously the rotating compaction head 115, and the chamber 107, are moved by hydraulic rams vertically upwardly along columns 111 as the grass builds up in the compaction chamber 107.
  • the compaction head 115 is operated to compact the material within the chamber 107 as described above. Simultaneously, the chamber 107 is raised vertically along the columns 111 by means of the hydraulic rams. The upward travel of the chamber 107 exposes the bottom portion of the partly- compacted bale 20 which rests on platform 130.
  • the film dispenser 194 is then rotated around the exposed cylindrical surface of the bale to wrap the bale, in well known manner, with plastics film from the dispenser and continues to operate until all of the exposed surface of the bale is wrapped, including an overlap of the bottom and top corners of the bale.
  • the compaction head 115 is driven by a chain drive which is substantially the same as the chain drive shown in Figures 10 and 11, and like numerals denote the like parts as shown in Figures 10 and 11. Also, the chain drive is constructed and operates substantially as described above with reference to Figures 9 to 11.
  • the main drive sprocket 70 is mounted at the lower end of the column (or mast) 111, and is powered from the power take-off shaft of a tractor via a gear box (not shown).
  • the vertically displaceable part comprises a sliding carriage 113 on which the support arms 112 are mounted.
  • the sliding carriage is moveable vertically along the column 111 by means of hydraulic rams (e.g. as indicated by reference numeral 29 in Figures 2 and 3 of WO 99/04613) to lift the compaction chamber 107 including the compaction head 115.
  • the head sprocket 72 is mounted in a bearing on the top of the vertically displaceable carriage 113, and moves upwardly and downwardly with the carriage 113.
  • the slide rod 74 is mounted on the fixed column 111. The operation of the chain drive is as described above with reference to Figures 9 to 11.
  • the head sprocket is keyed to a horizontal shaft 197 which transmits the drive to a right-angle gear box 198, which converts the drive from horizontal to vertical. From the gear box 198 a vertical shaft transmits the drive to an epicycle speed-reduction gear box 199 which drives the compaction rollers 115.
